The Race Tracker headphones from Koss provide high-quality audio and noise isolation in an extremely rugged design. Ideal for use by professionals who need a combination of durability and hearing protection, the Race Trackers have a hard plastic construction with a non-standard behind-the-head band and closed-back Pneumalite ear cushions to create a seal around the ear to block out ambient noise.

The headphones have neodymium drivers to provide high-quality audio with a wide frequency response. A built-in volume control on the earcup lets you make quick adjustments, while a mono/stereo switch lets you change between mono and stereo monitoring for terrific versatility. The single-sided coiled cable resists tangles and provides a variable amount of slack, while the standard 3.5mm stereo mini plug and 1/4" adapter provide compatibility with a wide variety of devices.
